Description

Technical Field

[0001] The utility model relates to the technical field of automatic calibration devices for mark-mounted pressure gauges, in particular to an automatic calibration device for mark-mounted pressure gauges. Background Art

[0002] The automatic calibration device for pressure gauges with marked installation is a device specially used for automatic calibration of pressure gauges. It can realize fast and accurate detection of pressure gauges and complete related operations such as mark installation during the calibration process, greatly improving work efficiency and calibration accuracy.

[0003] The existing related technologies often have the following defects: in the actual use of the automatic calibration device for the mark-mounted pressure gauge, the traditional sealing method of the automatic calibration device for the mark-mounted pressure gauge is to use a rotating sealing method. The staff needs to disassemble the calibration gauge and the pressure gauge separately to realize the subsequent sealing work of the calibration instrument, which reduces the sealing efficiency of the automatic calibration device for the mark-mounted pressure gauge.

[0004] Therefore, the utility model provides an automatic calibration device for a mark-mounted pressure gauge. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcoming in the prior art that it is inconvenient to quickly seal the automatic calibration device for the mark-mounted pressure gauge, and to propose an automatic calibration device for the mark-mounted pressure gauge.

[0006] In order to achieve the above-mentioned purpose, the present utility model adopts the following technical solutions: an automatic calibration device for a mark-mounted pressure gauge, comprising a calibrator, a calibration gauge and a pressure gauge being detachably mounted on the inner side of the calibrator, a driving structure being provided on the surface of the calibrator, the driving structure comprising a rectangular frame slidably mounted on the outer side of the calibrator, a sub-plate being rotatably mounted on the side wall of the rectangular frame, fan-shaped plates being rotatably mounted on both ends of the rectangular frame, a row of card slots being provided on the surface of the calibrator, and the size of the card slots being adapted to the size of the fan-shaped plates.

[0007] The effect achieved by the above components is: by setting up the driving structure, the flexible movement control of the rectangular frame is facilitated, which not only facilitates the covering and folding of the calibrator without disassembling the calibration gauge and pressure gauge, but also enables flexible support of the calibrator during use, thereby improving the performance of the calibrator.

[0008] Preferably, a connecting bar is fixedly connected to the side wall of the calibrator, a retaining frame is slidably connected to the inner side of the connecting bar, and a spring is fixedly connected to the surface of the connecting bar, and the spring is an arc-shaped structure.

[0009] The effect achieved by the above components is: press down the baffle frame, rotate the sub-plate on the calibrator to block the top side of the calibrator, release the baffle frame, and the baffle frame will pop out due to the elastic force of the spring clip on the connecting bar. At this time, the side position of the sub-plate can be limited and blocked.

[0010] Preferably, a plurality of reserved grooves are evenly formed on the surface of the sub-plate.

[0011] The above components have the following effects: the opened sub-plate can also be used as an operating platform to store measuring instruments, and the provision of reserved slots facilitates the storage of small parts that are prone to rolling off.

[0012] Preferably, silicone pads are glued to both sides of the fan-shaped plate.

[0013] The effect achieved by the above components is: by providing the silicone pad, the stability of the fan-shaped plate when the inner side of the card slot is turned into use is improved, thereby achieving the stability of controlling the position of the rectangular frame after movement.

[0014] Preferably, a portable structure is provided on the surface of the calibrator, and the portable structure includes a storage groove opened on the surface of the calibrator, two circular blocks are slidably connected to the inner side of the storage groove, and handles are fixedly connected to the surfaces of the two circular blocks.

[0015] The effects achieved by the above components are: by providing a portable structure, the flexible use of the handle is facilitated, and the subsequent carrying of the calibrator is facilitated, thereby facilitating the subsequent carrying of the calibrator.

[0016] Preferably, a plurality of anti-slip rings are evenly glued to the side wall of the handle.

[0017] The effects achieved by the above components are: the provision of the anti-slip ring increases the friction between the hand and the handle, thereby improving the stability of carrying the calibrator.

[0018] Preferably, the circular block and the bottom wall of the receiving groove are fixedly connected with a spring.

[0019] The effect achieved by the above components is that the circular block is driven by elastic force to drive the handle to slide out from the inner side of the storage slot.

[0020] In summary:

[0021] 1. In the present invention, when the calibrator needs to be sealed, the staff does not need to disassemble the calibration gauge and pressure gauge on the inside of the calibrator. They only need to slide the rectangular frame on the outside of the calibrator. When the rectangular frame moves to the position surrounding the calibration gauge and pressure gauge, the fan-shaped plate under the calibrator is rotated and the fan-shaped plate is turned into the inner side of the corresponding slot on the calibrator to achieve the shielding of the calibration gauge and pressure gauge. By setting a driving structure, the flexible movement and control of the rectangular frame is facilitated, which not only facilitates the shielding and folding of the calibrator without disassembling the calibration gauge and pressure gauge, but also enables flexible support of the calibrator during use, thereby improving the performance of the calibrator.

[0022] 2. In the utility model, during the process of folding the calibrator, after the rectangular frame moves to the position passing through the handle, the circular block will be driven by the elastic force to drive the handle to slide out from the inner side of the storage slot. The setting of the circular block avoids the phenomenon of the handle slipping from the inner side of the storage slot. At this time, the handle can be pulled. By setting up a portable structure, the flexible use of the handle is facilitated, and the subsequent carrying of the calibrator is facilitated, thereby facilitating the subsequent carrying of the calibrator.

[0029] Reference Figure 1As shown, the utility model provides a technical solution: an automatic calibration device for a marked mounted pressure gauge, comprising a calibrator 1, a calibration gauge 2 and a pressure gauge 3 being detachably mounted on the inner side of the calibrator 1, a driving structure 4 being provided on the surface of the calibrator 1, and a portable structure 5 being provided on the surface of the calibrator 1.

[0030] The specific configuration and functions of the driving structure 4 and the portable structure 5 will be described in detail below.

[0031] Reference Figure 1-Figure 4 As shown, in this embodiment: the driving structure 4 includes a rectangular frame 41 slidably mounted on the outside of the calibrator 1, a sub-plate 42 is rotatably mounted on the side wall of the rectangular frame 41, and fan-shaped plates 48 are rotatably mounted on both ends of the rectangular frame 41. A row of slots 47 are provided on the surface of the calibrator 1, and the size of the slots 47 matches the size of the fan-shaped plates 48. By setting up the driving structure 4, the flexible movement and control of the rectangular frame 41 is facilitated, which not only facilitates the shielding and folding of the calibrator 1 without disassembling the calibration gauge 2 and the pressure gauge 3, but also enables the flexible support of the calibrator 1 during the use of the calibrator 1, thereby improving the performance of the calibrator 1. The side wall of the calibrator 1 is fixedly connected to a connecting bar 44, the inner side of the connecting bar 44 is slidably connected to a baffle 45, and the surface of the connecting bar 44 is fixedly connected to a spring 46, which is an arc-shaped structure. Press down the baffle 45, rotate the sub-plate 42 on the calibrator 1, and after blocking the top side of the calibrator 1, release the baffle 45. The baffle 45 will be ejected by the elastic force of the spring piece 46 on the connecting strip 44. At this time, the side position of the sub-plate 42 can be limited and blocked. Several reserved grooves 43 are evenly opened on the surface of the sub-plate 42. The opened sub-plate 42 can also be used as an operating platform to store measuring instruments. The setting of the reserved grooves 43 facilitates the storage of some small parts that are easy to roll off. Silicone pads 49 are glued on both sides of the fan-shaped plate 48. By providing the silicone pads 49, the stability of the inner side of the card slot 47 being transferred to the fan-shaped plate 48 is improved, thereby achieving the stability of controlling the position of the rectangular frame 41 after movement.

[0032] Reference Figure 2 and Figure 5As shown, specifically, the portable structure 5 includes a storage groove 51 provided on the surface of the calibrator 1, and two circular blocks 54 are slidably connected to the inner side of the storage groove 51, and the surfaces of the two circular blocks 54 are fixedly connected with a handle 52. By providing the portable structure 5, the flexible use of the handle 52 is facilitated, and the subsequent carrying of the calibrator 1 is facilitated, thereby facilitating the subsequent carrying of the calibrator 1. Several anti-slip rings 53 are evenly glued to the side walls of the handle 52. The provision of the anti-slip ring 53 increases the friction between the hand and the handle 52, and improves the stability of carrying the calibrator 1. A spring 55 is fixedly connected to the circular block 54 and the bottom wall of the storage groove 51. The circular block 54 will be driven by the elastic force to drive the handle 52 to slide out from the inner side of the storage groove 51.

[0033] Working principle: when it is necessary to seal the calibrator 1, the staff does not need to disassemble the calibration gauge 2 and the pressure gauge 3 on the inside of the calibrator 1, but only needs to slide the rectangular frame 41 on the outside of the calibrator 1. When the rectangular frame 41 moves to the position surrounding the calibration gauge 2 and the pressure gauge 3, rotate the fan-shaped plate 48 under the calibrator 1, and turn the fan-shaped plate 48 into the inner side of the corresponding card slot 47 on the calibrator 1 to achieve the shielding of the calibration gauge 2 and the pressure gauge 3. By setting the silicone pad 49, the stability of the use of the fan-shaped plate 48 turned into the inner side of the card slot 47 is improved, thereby achieving the stability of controlling the position of the rectangular frame 41 after movement. At this time, press down the baffle frame 45, rotate the sub-plate 42 on the calibrator 1, and after blocking the top side of the calibrator 1, release the baffle frame 45. The baffle frame 45 will be ejected by the elastic force of the spring piece 46 on the connecting strip 44. At this time, the side position of the sub-plate 42 can be limited and blocked to avoid The twisting of the sub-plate 42 is eliminated, thereby realizing the covering work of the calibrator 1. When the calibrator 1 is opened for use, the rectangular frame 41 is lowered. The staff can adjust the different heights of the calibrator 1 by adjusting the distance between the lowered rectangular frame 41 and the calibrator 1. The fan-shaped plate 48 above the rectangular frame 41 is rotated, thereby facilitating the support work of the calibrator 1 at different heights. At this time, the opened sub-plate 42 can also be used as an operating platform to realize the storage work of the measuring instrument. The setting of the reserved groove 43 facilitates the storage work of some small parts that are easy to roll off. By setting the driving structure 4, the flexible movement control work of the rectangular frame 41 is facilitated, which not only facilitates the covering and folding work of the calibrator 1 without disassembling the calibration gauge 2 and the pressure gauge 3, but also realizes the flexible support work of the calibrator 1 during the use of the calibrator 1, thereby improving the use performance of the calibrator 1.

[0034] When the calibrator 1 is folded up, after the rectangular frame 41 moves to the position passing through the handle 52, the circular block 54 will be driven by the elastic force to drive the handle 52 to slide out from the inner side of the storage slot 51. The setting of the circular block 54 prevents the handle 52 from slipping off the inner side of the storage slot 51. At this time, the handle 52 can be pulled up. The setting of the anti-slip ring 53 increases the friction between the hand and the handle 52, and improves the stability of carrying the calibrator 1. Conversely, the handle 52 is pressed back to the inner side of the storage slot 51, and the rectangular frame 41 is used to cover the handle 52, and the handle 52 is blocked on the inner side of the storage slot 51, so that the hidden installation of the handle 52 can be realized. By setting the portable structure 5, the flexible use of the handle 52 is facilitated, and the subsequent carrying of the calibrator 1 is facilitated, thereby facilitating the subsequent carrying of the calibrator 1.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
